Question

How can I block Google Images searches with SafeSearch turned off?

Environment

Cisco Web Security Appliance (WSA), all versions of AsyncOS

Solution

With Safe Search option disabled on WSA, in order to block Google images on Google, you need to create a new custom URL category using the following regular expression:

www.google.*/imghp\?hl=
google.*/.*&tbm=isch

Afterwards please make sure that all requests to Google are decrypted by the appliance.
